This story from Oklahoma City is about the influx of Californians there, but the statistics apply to Dallas as well:
From 2004 through 2007, about 275,000 Californians left the Golden State for the old Dust Bowl states of Oklahoma and Texas, twice the number that left those two states for California, recent Internal Revenue Service figures show. In fact, the mid-South gained more residents from California during those four years than either Oregon, Nevada or Arizona. The trend continued into 2008.
